Discrete Output Module Allen-Bradley 1746-OBP8 SLC 500 8 Outputs

Product Overview

The Allen-Bradley 1746-OBP8 is a digital DC output module for the SLC 500 platform. It provides eight source outputs. Each output handles up to 2.0A at 60°C. This module works with 20.4 to 26.4 Volts DC. It is ideal for demanding industrial applications. The module uses two isolated groups of four points each. This design simplifies wiring and troubleshooting. The 1746-OBP8 offers fast signal response times. It turns on in 1.0 ms and off in 2.0 ms. The module dissipates only 0.3 Watts of power. It supports a surge current of 4A for 10 ms. The on-state voltage drop is a maximum of 1V at 2A. This ensures efficient power delivery to your loads.

Application Scenarios

Use the 1746-OBP8 module for high-current DC load control. It works well with solenoids, relays, and motor starters. The module is suitable for conveyor systems and packaging machines. It controls industrial valves and indicators. The SLC 500 platform fits many factory automation tasks. The module operates reliably in temperatures from 0 to 60°C. It withstands 30g of shock. This makes it perfect for heavy machinery environments. The module also handles 5 to 57 Hz vibration. Use it in automotive, food processing, and material handling plants. The 1746-OBP8 provides robust output switching for critical processes.
